Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a special tooling for manufacturing ship deck railings. Background Technology

[0002] Ship deck railings are an important component of the ship's superstructure, serving multiple functions such as safety protection, personnel passage, and ship mooring. Their structure is typically welded together from components such as columns, handrails, and crossbars (or railings), forming a typical spatial frame structure. Specialized tooling is required to secure the components during the welding process.

[0003] Referring to Chinese Patent Publication No. CN216887118U, published on July 5, 2022, a standardized installation fixture for ship main deck railings is disclosed. Addressing the shortcomings of existing technologies where ship main deck railings are typically installed by welding or bolting, which is cumbersome, time-consuming, labor-intensive, increases worker workload, reduces efficiency, and lacks stability, this invention proposes a solution comprising a connecting box and a railing. The bottom end of the railing penetrates the top of the connecting box and extends into its interior. Pressure bars are fixedly connected to the left and right sides of the railing, with the bottom ends of both pressure bars penetrating the top of the connecting box and extending into its interior. This invention achieves rapid assembly and disassembly of the railing through a simple structure, offering convenient operation, saving time and effort, while also ensuring higher stability, usability, and practicality after installation.

[0004] The existing technology has the following technical problems: the existing special tooling for manufacturing ship deck railings is not convenient for adjusting the height of the tooling table, and its functionality and convenience need to be improved, as does the stability of clamping and fixing components. Therefore, we propose a special tooling for manufacturing ship deck railings to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special tooling for manufacturing ship deck railings, comprising a workbench, an adjustable support structure, and a limiting structure. The adjustable support structure is installed at the bottom of the workbench, and the limiting structure is installed inside the adjustable support structure. V-blocks and a movable structure are fixedly installed on both the left and right sides of the top of the workbench. The V-blocks are located in front of the movable structure, and a clamping structure is provided at the top of the V-blocks. The clamping structure is fixedly connected to the movable structure. The limiting structure includes a limiting rod, a threaded rod, and a nut. The limiting rod is fixedly connected to the threaded rod at both ends, and the nut is threadedly connected to the outer side of the threaded rod.

[0007] Preferably, the adjustable support structure includes an inner support plate, an outer support plate, and positioning holes. The inner support plate is slidably connected inside the outer support plate, and equidistant positioning holes are provided in the walls of both the inner and outer support plates.

[0008] Preferably, a workbench is fixedly connected to the top of the inner support plate.

[0009] Preferably, the clamping plate structure includes a mounting plate, connecting rods, clamping blocks, and springs. Multiple connecting rods are slidably connected inside the mounting plate, and the mounting plate and clamping blocks are fixedly connected to the top and bottom ends of the springs, respectively.

[0010] Preferably, the connecting rod is fixedly connected to the clamping block.

[0011] Preferably, the movable structure includes an automatic telescopic rod, a first fixed rod, and a second fixed rod. The output end of the automatic telescopic rod is fixedly connected to the first fixed rod, and the end of the first fixed rod away from the automatic telescopic rod is fixedly connected to the second fixed rod. The automatic telescopic rod is fixedly installed on the top of the workbench.

[0012] Preferably, a mounting plate is fixedly connected to the bottom end of the second fixing rod.

[0013] Preferably, the automatic telescopic rod is fixedly installed on the top of the workbench.

[0014] Preferably, the limiting rod is disposed through the positioning hole.

[0015] As a preferred technical solution of this utility model, the adjustable support structure includes an inner support plate, an outer support plate and positioning holes. The inner support plate is slidably connected inside the outer support plate. The inner support plate and the outer support plate are both provided with equidistant positioning holes. A worktable is fixedly connected to the top of the inner support plate.

[0016] By adopting the above technical solution, the inner support plate is slidably connected to the outer support plate. The height of the worktable is adjusted by moving the inner support plate up and down, and the positioning holes in the inner support plate are aligned with those in the outer support plate.

[0017] As a preferred technical solution of this utility model, the limiting structure includes a limiting rod, a threaded rod, and a nut. The limiting rod is fixedly connected to the threaded rod at both ends, and the nut is threadedly connected to the outer side of the threaded rod.

The output end of the automatic telescopic rod is fixedly connected to the first fixed rod, and the end of the first fixed rod away from the automatic telescopic rod is fixedly connected to the second fixed rod.

[0022] By adopting the above technical solution, the automatic telescopic rod drives the second fixed rod to move up and down, which in turn drives the mounting plate to move up and down, which in turn drives the clamping block to move up and down, thereby allowing the clamping block to clamp and fix or release the rod.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects: the special tooling for manufacturing ship deck railings, through the adjustable support structure and the limiting structure, facilitates the adjustment of the height of the workbench. At the same time, when the limiting rod passes through the positioning holes of the adjustable support structure on both sides, multiple limiting rods can form a horizontal platform, which is convenient for placing items, thereby improving functionality and convenience.
